Cloud clients (CCs) of current distributed cloud applications are still not assured of their service quality, in particular, in terms of the experienced latency. Unfortunately, this is mainly attributed to the unpredictability of the communication links among their hosting distributed data centers. To address this problem, this article introduces a novel virtual-network-as-a-service (VNaaS) model to […]

The Application of SOM Network to Particle Tracking Velocimetry in a Wind-Blown Sand Flow
Wind-blown sand flow is the basic phenomena that have profound influences on the environment, and the experimental study on the velocity distribution of the sand particles is very important for the understanding of this phenomena. Among the various experimental techniques, particle tracking velocimetry (PTV for short) is one that attracts more and more attentions. In […]
Read moreThis paper addresses an important aspect of mobile core network virtualization: The combined optimization of the virtual mobile core network topology (graph) and its embedding onto a physical substrate network. Basically this comprises the placement of mobile core virtual network functions (VNFs) onto the nodes of the physical substrate network, the determination of the interconnections […]
Read moreThe present note investigates the stabilization, controllability and optimal control problem of Boolean networks with impulsive effects and state constraints. By using the semi-tensor product method, the algebraic form of the Boolean networks with impulsive effects and state constraints is derived. The stabilization and controllability issues of the systems are investigated and some necessary and […]

Distribution Network Verification for Secure Restoration by Enumerating All Critical Failures
If several feeders are interrupted in a severe accident, distribution networks should be restored by reconfiguring switches automatically with smart grid technologies. Although there have been several restoration algorithms developed to find the new network configuration, they might fail to restore the whole network if the network were critically damaged. The network’s design has to […]
